BACKGROUND ART

Anaplastic Lymphoma Kinase (ALK) is one of the receptor tyrosine kinases belonging to insulin receptor family (Non-Patent Document Nos. 1 and 2).

It was reported that, due to gene alteration of ALK (translocation, point mutation and gene amplification), an abnormal activation of ALK is eventually involved in oncogenesis.

For example, in lung cancer, ALK forms EML4-ALK due to chromosomal translocation, leading to constitutive activation of tyrosine kinase, and it acquires a tumorigenic activity (Non-Patent Document 1). In addition, the ALK translocation were reported in systemic anaplastic large cell lymphoma (ALCL) and inflammatory myofibroblastic tumors (IMTs) (Non-Patent Document Nos. 3 and 4), and esophageal cancer (Non-Patent Document 5). It was also found that active point mutation (approximately 10%) or gene amplification of ALK is involved in oncogenesis of neuroblastoma (Non-Patent Document Nos. 6 and 7).

On the other hand, it was also reported in tumors activated by pleiotrophin (PTN) or midkine (MK) (Non-Patent Document Nos. 8 and 9), both a ligand for ALK.

Further, from the study using ALK knock-out mouse, it was suggested that an inhibitor for ALK is useful as an anti-depression agent or as a preventive or therapeutic agent for cognitive function disorders (Non-Patent Document 10 and Patent Document 1).

Therefore, a compound having an inhibitory activity on ALK will be very useful for the prevention and treatment of cancer, depression and cognitive function disorders, etc.

Meanwhile, as an ALK inhibiting material, there are some compounds among multi-kinase inhibitors which have an inhibitory activity on ALK as one of their activities. For example, as an inhibitor for c-MET (mesenchymal-epithelial transition factor) and ALK, PF02341066 having a 2-aminopyridine structure was reported (Patent Document 2, Non-Patent Document Nos. 11 and 12). As an inhibitor for FAK, ZAP70, IGF-1R and ALK, etc., NVP-TAE684 having a 2,4-diaminopyrimidine structure was reported (Patent Document 3 and Non-Patent Document 13). In addition, 2,4-diaminopyrimidines and 2,4-diaminoquinazolines (Patent Document 4), pyridopyrazines (Patent Document 5), pyrazolo [3,4-C] isoquinolines (Patent Document 6), thiazoles (Patent Document 7), tricyclic compounds (Patent Document 8), and indazoles (Patent Document 9) and the like have been reported.

However, the tetracyclic compounds of the present invention are not disclosed in any of the documents described above.

As a tetracyclic compound exhibiting an anti-tumor activity, tetracyclic compounds comprising carbazole structure like ellipticine are known.

However, their action mechanism is based on interaction with DNA to exhibit cell toxicity (Non-Patent Document 15), and there is no description at all regarding the activity of inhibiting ALK by the tetracyclic compounds.

Preferably, the salts are pharmaceutically acceptable salts. These salts are produced by brining the compounds described above in contact with an acid or a base which can be used for the production of a pharmaceutical product.

According to the present invention, the compounds that are represented by the Formula (I) or salts thereof can be an anhydride or a solvate such as a hydrate and the like. Herein, the term “solvate (d)” indicates a phenomenon by which solute molecules or ions contained in a solution strongly attract neighboring solvent molecules to form a huge group of molecules. When the solvent is water, it is called “hydrate (d).” The solvate can be any one of a hydrate and a non-hydrate. Preferably, the solvates are pharmaceutically acceptable solvates. For the non-hydrate, alcohol (for example, methanol, ethanol, n-propanol), dimethylformamide and the like can be used.

The compounds of the present invention and salts thereof may be present in several tautomer forms, for example, enol and imine form, keto and enamine form, and a mixture thereof. In a solution, a tautomer is present as a mixture of tautomeric set. In case of solid form, one type of tautomer is generally present in dominant ratio. In this regard, even if only one type of tautomer is described, the present invention includes all types of tautomer of the compounds of the present invention.

The present invention includes all types of stereoisomer of the compounds of the present invention that are represented by the Formula (I) (for example, enantiomer, diastereomer (including cis and trans geometric isomer)), racemate of the isomer and a mixture thereof. For example, the compounds having the Formula (I) of the present invention may have one or more asymmetric center, and the present invention includes a racemic mixture, a diastereomer mixture and enantiomer of such compound.

When the compounds of the present invention are obtained in free form, they can be converted into a salt, a hydrate or solvate thereof which can be formed from the compounds according to a method generally known in the art.

Further, when the compounds of the present invention are obtained in the form of a salt, hydrate or solvate of the compounds, they can be converted to free form according to a method generally known in the art.

The present invention include all isotopes of compounds that are represented by the Formula (I). The isotopes of the compounds of the present invention indicate the compounds of the present invention in which at least one atom is substituted by an atom with the same atomic number (i.e., number of protons) but with different mass number (sum of the number of protons and the number of neutrons). Example of the isotopes that are included in the compounds of the present invention includes a hydrogen atom, a carbon atom, a nitrogen atom, an oxygen atom, a phosphorus atom, a sulfur atom, a fluorine atom, a chlorine atom and the like, and ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁷O, ¹⁸O, ³¹P, ³²P, ³⁵S, ¹⁸F, ³⁶Cl and the like are included. In particular, a radioisotope which decays by emitting radiation, for example ³H and ¹⁴C, are useful for determining the distribution of a pharmaceutical agent or a compound in a living tissue, etc. On the other hand, a stable isotope does not degrade and remains in almost the same amount without exhibiting radioactivity, and therefore can be safely used. Isotopes of the compounds of the present invention can be converted by replacing a chemical reagent used for synthesis with a chemical reagent comprising a corresponding radioisotope according to a method generally known in the art.

Further, the compounds (I) of the present invention can be administered in the form of prodrug. Herein, the term “prodrug” indicates the derivatives of the compounds having the Formula (I) that can be converted to the compounds having the Formula (I) or salts or solvates thereof after administration by enzymatic or non-enzymatic degradation under a physiological condition. The prodrug can be in inactive form when it is administered to a patient. However, in organisms, it converts to the compounds having the Formula (I) and present therein in the active form.

For example, the prodrug converts into desired drug form at specific pH or by an enzymatic action. Conventional prodrug is a compound having a hydrolyzable ester residue which produces a free acid in organisms. Examples of such hydrolyzable ester residue include a residue having a carboxyl moiety of which free hydrogen (for example, a free hydrogen in a carboxyl group when Y in the Formula (I) has a carboxyl group) is replaced by a C₁₋₄ alkyl group, a C₂₋₇ alkanoyloxymethyl group, a 1-(alkanoyloxy)ethyl group having 4 to 9 carbon atoms, a 1-methyl-1-(alkanoyloxy)-ethyl group having 5 to 10 carbon atoms, an alkoxycarbonyloxymethyl group having 3 to 5 carbon atoms, a 1-(alkoxycarbonyloxy)ethyl group having 4 to 7 carbon atoms, a 1-methyl-1-(alkoxycarbonyloxy)ethyl group having 5 to 8 carbon atoms, a N-(alkoxycarbonyl)aminomethyl having 3 to 9 carbon atoms, a 1-(N-(alkoxycarbonyl)amino)ethyl group having 4 to 10 carbon atoms, a 3-phthalidyl group, a 4-crotonolactonyl group, a γ-butyrolacton-4-yl group, a di-N,N—(C₁₋₂)alkylamino(C₂₋₃)alkyl group (for example, N,N-dimethylaminoethyl group), a carbamoyl(C₁₋₂)alkyl group, a N,N-di(C₁₋₂)alkylcarbamoyl-(C₁₋₂)alkyl group, a piperidino(C₂₋₃)alkyl group, a pyrrolidino(C₂₋₃)alkyl group, or a morpholino(C₂₋₃) alkyl group, but not limited thereto.

Microwave Reaction

The reaction was carried out by using a snap cap reaction vial together with an Explorer™ (manufactured by CEM Microwave Technology) or an initiator (manufactured by Biotage). Maximum output setting includes cooling of the reaction vessel by air in order to avoid temperature increase caused by microwave irradiation.

Commercially available reagents were obtained and used without any further purification. The room temperature indicates the temperature range of between about 20 to 25° C. All the non-aqueous reaction was carried out in anhydrous solvent under nitrogen or argon atmosphere. For concentration under reduced pressure or removal of a solvent by distillation, a rotary evaporator was used.

For preparing the compounds, when there is a possibility of having an undesirable side reaction, a functional group was protected using a protecting group to produce a target molecule, and the protecting group was removed later, if desired. Selection, addition and removal of a protecting group were carried out according to the method described in the literature [Greene and Wuts, “Protective Groups in Organic Synthesis” (4^(th) edition, John Wiley & Sons 2007)], for example.

1. Activity of Inhibiting ALK Enzyme

ALK-inhibiting activity was measured by following an activity of inhibiting phosphorylation by biotinylated peptide (EGPWLEEEEEAYGWMDF). For the detection of phosphorylation of the biotinylated peptide, time-resolved fluorescence measurement was performed using an anti-phosphorylated tyrosine antibody labeled with europium cryptate and streptavidin conjugated to XL665, i.e., an allophycocyanin derivative. From the inhibition ratio compared to the control group that does not comprise a test compound, 50% inhibitory concentration (i.e., IC₅₀ value) was calculated.

2. Measurement of an Activity of Inhibiting Karpas-299 Cell Growth

The test compounds were serially diluted with dimethyl sulfoxide, further diluted with phosphate buffered saline which is free of any Ca²⁺, Mg²⁺ (×50 dilution), and 10 μL of the resulting solution was aliquoted in a 96-well plate. Human lymphoma cell line KARPAS-299 was prepared in RPMI-1640 medium to which 10% bovine fetal serum was added to give a cell suspension with the cell density of 10,000 cells/190 μL. The resulting cell suspension was aliquoted to the plate (190 μL per well) to which the test compound had been already added, and the plate was kept in a 5% carbon dioxide gas incubator at 37° C. Ninety-six hours later, 10 μL of WST-8 (manufactured by Dojindo Laboratories) was added to each well, and subsequently the absorbance was measured at 450 nm. From the ratio of inhibition on cell growth which had been obtained from the addition of a test compound compared to the control group with no addition, 50% growth inhibitory concentration (i.e., IC₅₀ value) of the test compound was calculated.
